gene-fusions-nf

A nextflow pipeline to call somatic rna fusions from RNA-seq data using arriba

Dependencies

  1. Nextflow : for common installation procedures see the IARC-nf repository.
  2. arriba

A conda receipe, and docker and singularity containers are available with all the tools needed to run the pipeline (see "Usage")

Input

Type Description
reads Path to input data
bams Path to folder containing BAM files for processing

Parameters

  • Mandatory

Name Example value Description
ref_fa ref.fa Path to fasta reference
ref_gtf annot.gtf Path to GTF annotation
star_index index/ Path to STAR-Index reference
  • Optional

Name Default value Description
reads_csv NULL file with tabular data for each sample to process
svs NULL file with tabular data for each sample with structural variants in bedpe format
  • Flags

Flags are special parameters without value.

Name Description
--arriba_plot by default plot all the gene fusions detected by arriba. set to false to deactivate
--help Display help

Usage

nextflow run  iarc/nf-gene-fusions -r v1.1 -profile singularity --reads 'test_dataset/reads/*.R{1,2}.fastq.gz' --ref_fa test_dataset/genome.fa --ref_gtf test_dataset/genome.gtf
  or
nextflow run  iarc/nf-gene-fusions -r v1.1 -profile singularity --bams '/path/to/bams/' --ref_fa test_dataset/genome.fa --ref_gtf test_dataset/genome.gtf

To run the pipeline without singularity just remove "-profile singularity". Alternatively, one can run the pipeline using a docker container (-profile docker) the conda receipe containing all required dependencies (-profile conda).

Output

Type Description
outdir Folder with fusion genes file
